PHOTOGRAPHIC APPARATUS.

SPECIFICATION forming part of Letters Patent No. 424,315, dated March 25, 1890.

Application filed May 29, 1889.

T at whom it may concern.-

Be it known that we, EMIL KIPPER, a subject of the Emperor of Germany, (having declared his intention to become a citizen of the United States,) residing at Adams, county of Berkshire, and State of Massachusetts, and ENOOH 'WOOD PERRY, Jr., a citizen of the United States, residing at New York, in the county of New York and State of New York,

operated externally and without the necessity of opening either the plate-holder or the receiver.

It is the purpose of our invention to simplify and improve the construction and oper- 2 5 ation of apparatus of this character; and to this end said invention consists in the several novel features of construction and new combinations of parts, hereinafter fully set forth, and then defined in the claims following this specification.

Referring to the accompanying drawings, Figure 1 is a perspective view of a plate holder and receiver with a camera attached embodying our invention. Fig. 2 is a per- 3 5 spective view of the plate holder and receiver detached. Fig. 3 is a substantially central longitudinal section of Fig. 1. Fig. dis a de tail plan view showing a part of the shiftingframe with its actuating-gear. Figs. 5 and G are detail views showing features of construction.

In the said drawings, the reference-numeral 1 designates a plate holder or receptacle of any convenient form and having such con- 5 struction that it may be attached to or form part of a camera 3. Arranged upon one side of the plate-holder is a plate-receiver 4, which may either be detachably connected with or form a permanent part of the plate-holder, from which it is separated by a wall or walls Serial No. 312,569. (No model.)

5. \Vithin the plate-holder is a support 6, upon or against which a pile of sensitized plates or films 7 may be placed, said support being capable of adj ustmtnt by any suitable means-such, for example, as a screw 8for which a spring or springs may be substituted, if preferred. The front of the plate-holder is closed by a slide 9, which effectually excludes the light, and within said slide are formed grooves or channels 10, which receive the par allcl sides of a sliding frame 12, which is capable of moving in said channels and in c011- tinuations thereof formed in or upon the walls of the plate-receiver, openings being formed in the wall or walls '5 to receive the arms or bars of the frame. The sensitized plates or films 7 as they are fed forward by the adjustment of the support 6 rest against a flange or narrow strip 13, projecting from the inner face of the plate-holder at its end, and, if desired, similar flanges may be applied to both the adjacent walls, and may extend thereon the entire length of the plates or only part of that distance.

Upon the inner face of the bars 14 of the 7 5 frame 19 are formed or mounted teeth or proj ections 15,which extend far enough from the said bars to engage the surface of the outerplate or film as it is pressed by the support 6 against the narrow flanges 18. These teeth may be formed in various ways. For example, if the frame 12 is of wood, the teeth may consist of metal points set in the wood and inclined with relation to the surface of the plate in such manner that they may slide over said plate 8 5 without engagement when moved in one dircetion, and may, when the frame slides in an opposite direction, either engage the plate or exert such a degree of friction thereon as to compel the plate to move with the frame. When the latter is constructed of metal, a very convenient method of forming these teeth or projections is to place the sharp point of a triangular punch upon the bar, inclining it at a small angle thereto, and strike a 5 smart quick blow upon the tool,thereby raising a triangular point of metal, which inclines and points in the direction of the plate-receiver. These points slide easily over the surface of the plates as the frame is pushed in Too ward, but engage therewith as it is drawn out ward. \Ve may, however, form these projections in any othermanner and of any suitable material, and they may be rigid, as described, or mounted upon pivots and arranged in sockets, in which they may turn freely as the frame is pushed inward, while in the opposite movement of the frame they are turned to project outward and held by the rear walls of the sockets in position to act upon the plate. This construction is illustrated in one form in Fig. 5.

The frame 12 is moved in both directions by a pinion 16, carried by a shaft 17 mounted in suitable bearings, preferably upon the exterior of the box, said pinion being inclosed or incased to exclude light. The pinion lies partly in a slot cut in the wall of the plateholder, and its teeth mesh with a rack 18, formed or mounted upon the edge of the frame.

- The plate-receiver 4 maybe closed by a slide or by any suitable form of cover 19, upon which is mounted a plate-detaching device, whereby the plate or film as it is withdrawn by the frame 12 and brought into the receiver may be detached from the teeth or the frame, to which the plates sometimes adhere. The detaching device may be wholly automatic, and may consist of one or more springs 20, mounted upon the cover. It may also be formed of a plunger 21, of any suitable form, passing through the cover and projected outward by a spring 22. A plate or pad 23 may be mounted on the inner end of the plunger, which is pushed inward by the operator as the frame is thrown out of the plate-holder.

As the plates are withdrawn one at a time, they pass through an opening 24C in the wall or walls 5, which is preferably made of such width as to permit the passage of only one plate at a time. This slot may be closed by a flap 25, opening outward into the plate-re ceiver and closed by a spring or by any other suitable means.

The plates may be either rigid or flexible, and in some cases they maybe provided with an envelope, formed of tin or other metal, vulcanized rubber, zylonite, paper, or other material, and having two or more of its margins turned over upon the outer face of the plate. In this form of construction the teeth or projections of the frame 12 will engage with the flanges or margins of the envelope instead of with the face of the plate.

In using this apparatus the slide of the plate-holder is withdrawn to expose the plates, and when the exposure is completed a turn is given to the shaft 17, thereby throwing the frame into the receiver at and carrying with it the outer or exposed plate, which is pushed back in the receiver by the detaching device out of the way of the next plate to be re moved. The frame is then returned to its original position and a second exposure made, the pile or stack of plates being fed forward meantime by the support 6.

lVe do not claim herein anything that claimed in our application for Letters Patent No. 304,145, filed March 21, 1889.

hat we claim is 1. 111 a photographic apparatus, the com bination, with a plate holder and receiver, of a plate-transferring device having teeth or projections which engage the plate when moving in one direction, and inclosed gearing meshing with a rack upon the transferring device, substantially as specified.

2.
